As the White House scrambles to deny reports that President Donald Trump revealed highly classified intelligence to Russian Foreign Ministry officials, the chief executive took to Twitter for his own response.

Trump said as president he has the "absolute right" to share "facts pertaining to terrorism and airline flight safety," citing "humanitarian reasons" and a desire for Russia to ramp up its efforts to combat ISIS.

The concern by intelligence officials and lawmakers following the Monday night reports from The Washington Post and The New York Times that cite U.S. officials who say Trump may have jeopardized a source of the information last week in a meeting with Russia's foreign minister and an ambassador.

H.R. McMaster, Trump's national security adviser who participated in the meeting, spoke with White House reporters Monday night.

"At no time were intelligence sources or methods discussed and the president did not disclose any military operations that weren't already publicly known," he said. "I was in the room. It didn't happen."

Secretary of State Rex Tillerson sent a statement regarding the report:

"During President Trump’s meeting with Foreign Minister Lavrov a broad range of subjects were discussed among which were common efforts and threats regarding counter-terrorism. During that exchange the nature of specific threats were discussed, but they did not discuss sources, methods or military operations."

Lawmakers leading investigations into alleged Russian meddling into the 2016 election had were bothered by the reports.
